Fruit salad which costs $3/lb is made by combining sliced peaches which cost $2/lb with sliced bananas which cost $6/lb. Find the number of lb of sliced peaches and sliced bananas required to make 12 lb of fruit salad.
\n" ); document.write( "so we will call x number of lbs of sliced peaches and y number of lbs of sliced bananas
\n" ); document.write( " $\"2x%2B6y=12%2A3\"$
\n" ); document.write( " $\"x%2By=12\"$ now we have to solve this system of equations
\n" ); document.write( " $\"x=12-y\"$
\n" ); document.write( " $\"2%2812-y%29%2B6y=12%2A3\"$
\n" ); document.write( " $\"24-2y%2B6y=36\"$
\n" ); document.write( " $\"24%2B4y=36\"$
\n" ); document.write( " $\"4y=36-24\"$
\n" ); document.write( " $\"4y=12\"$ divide both sides by 4
\n" ); document.write( " $\"y=3\"$ so since we said earlier that x=12-y then
\n" ); document.write( " $\"x=12-3\"$
\n" ); document.write( " $\"x=9\"$
\n" ); document.write( "so we need 9 lbs of peaches and 3 lbs of bananas \n" ); document.write( "

\n" );
